2020 MBS 2401 Dometic water heater drain plug

Drained my 6 gallon gas/electric hot water tank for the first time and noticed that there was no zinc rod in the drain plug. Should there be or does this unit not use a zinc? Click image for larger version

Your tank is aluminum and has no need for an anode rod....which is why it doesn't have it

It's the Suburban brand with their porcelain lined steel tanks that require an anode rod

You are very welcome. This question does come up since we have so many threads on suburban brands and their anode rods.

Here is a screenshot from dometic.com about their tank type water heaters and the aluminum tanks they use.Click image for larger version
